MACHINE FOR WRAPPING BBOACHES AND THE LIKE.

Specification of Letters Patent.

Patented Aug. 8, 1916.

Application filed June 2, 1916. Serial No. 101,430.

To all whom it may concern Be it known that I, LEVI L. FUNK, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful 1m orovements in Machines for rapping roaches and the like, of which the following, when taken in connection with the drawing accompanying and forming a part hereof, is a full and complete specification, suflicient to enable those skilled in the art to which it pertains to understand, make, and use the same.

To those familiar with the use of broaches in cleaning the nerve channels of teeth it is well known that great care should be observed to maintain a sterilized condition of the fiber which is wrapped around the broach.

llhe object of this invention is to obtain a machine by means of which fiber may be easily, rapidly, effectually, and properly wound on a broach for use by dentists, and by means of which contact of the hands with said fiber is obviated.

A further object is to obtain a device of the kind named which requires no particular skill on the part of the operator to use the same, and a device which is easily installed on an ordinary electric circuit.

A further object is to obtain a device of the kind named which comprises few parts not liable to break or get out of order.

I have illustrated a device embodying this invention in the drawing referred to, in which 7 i Figure 1, is a top plan view with a wrappingmember thereof in an inoperative position and an additional wrapping member in an operative position. Fig. 2, is a side elevation with the several parts in the position in which they are illustrated in Fig. 1. Fig. 8, is a topplan view in an operative position, of the wrapping member which is illustrated in Figs. 1 and 2 in an inoperative position, together with cooperating elements and Fig. 4B, is a vertical section on line H of Fig. 3, viewed in the direction indicated by the arrows.

A, is a base on which the several members of the device are mounted.

B is the base of an electric lamp, and 7) designates a switch in said base.

C is an electric lamp in base B,

D is an electric motor.

E is an incoming line wire and c an outgoing line wire.

The motor D is cut into the outgoing line wire 6, so that the lamp C, and the motor Dam in series. The purpose of mounting sa1d lamp and motor in series is to reduce the speed'of the motor D and hence a lamp of suitable resistance to obtain the desired operative speed of motor D is used.

F is the armature shaft of motor D, and 7 is a driving pulley on shaft F.

The motor D is attached to the base A, by bolt G, so that it can be turned from the position thereof which is illustrated in Fig. 1, into the position which is illustrated in Flg. 3; and 9 represents a ball bearing in terposed between said base and motor around said bolt G.

H is a plate which is attachedto one end of the casing of the motor D.

I represents a link which connects the plate H to switch Z) so that the turning of motor D from the position thereof in which it is illustrated in Figs. 1 and 2 into the position which is illustrated in Fig. 3, closes said switch in base B.

J is a pulley which on plate H and j is a pulley 7 to pulley J.

is an idler, to belt j.

The pulley J is provided with a central aperture K therethrough, and a bell shaped projection 70 is rotatably mounted belt extending from on one side thereof.

L represents an elastic lining to aperture K, as cork or rubber.

M represents a broach and m a handle to the broach. The handle m fits closely in apertureK and is turned by the turning of the pulley J.

Assuming the motor D to be in substantially the position illustrated in Figs. 1 and 2; that a broach (M) is inserted in aperture K so that its handle fills said aperture or is seated therein, and after said insertion, pressure is applied to the plate H on which the pulley J is mounted, so as to bring the motor D, plate H, pulley J, and link I into substantially the position in which said parts are illustrated in Fig. 3, the broach M will be in position to engage with fiber between plates N and a, the switch 6 closed and the motor D will be operated.

O is a fiber receptacle provided with the slot 0 (see Fig. 4).

P is a hook provided with barb p and 3,19

slot 79 which is mounted on base A, and secured thereto by thumb nut P. The hook P may be moved from the position in which it is illustrated in full lines in Figs. 1 and 3 into the position which is indicated by broken lines in Fig. 1, and from thence back to its initial position. When hook P is in the position indicated by broken lines in Fig. 1,

barb p is in the slot 0 of receptacle 0 and is in contact with fiber in said receptacle, and by drawing said barb out from said position some of said fiber may be drawn through said slot 0 and deposited underneath the'plate N, before said hook P is returned to its initial position. lVhen the broach M (in aperture K of the pulley J) is in the position illustrated in Fig. 3, it is made to rotate by the rotation of the motor D, and one end of said broach being in position to engage with the fiber R, by the turning of said pulley J said broach is turned and said fiber is wrapped around the broach.

An electric current to operate the motor D, as hereinbefore described, is not at all times obtainable and at such times the member D may be used as a substitute for the motor D. Member D comprises a case or shell, a ribbon d, and a spring d to which one end of the ribbon d is attached.

S is a wire which is provided with a loop against (or in which as preferred), the broach M may be placed when it is to be rotated by means of the ribbon (Z. The ribbon (Z being brought over the broach M, substantially as in Figs. 1 and 2, of the drawing,'the pulling of said ribbon out from the shell of member D tends to turn the broach M and to wind spring d. When the ribbon (Z is released said spring d will draw said ribbon back into member D, and the operation of pulling the ribbon D out of said member and permitting it to be returned thereinto is continued until the fiber I is wound on said broach M.

S, is a spring. S, S are screws. Adetermined downward pressure of spring S on leaf N may be obtained by turning the screw S into base A.

T is a plate which is placed over plate N and forced onto said plate N (by means of screw 8") and on to the additional flexible plate U, to hold said plates N and U in position.

hen the barbed end 29 of hook P is inserted in slot 0 or retracted therefrom it moves between plates N, n and also between plate U and base A. By pressure of the finger on plate U during the time the hooked end 31, after being retracted from the aperture O, is moved underneath the plate U some of the fiber will be stripped from said hook, said stripped fiber being retained underneath said plate U. Increase of the pressure on plate U will decrease the quantity of fiber which is thereby stripped from book 19. Hence, this plate U afiords means to control the quantity of fiber which is deposited between the plates N, n by said hook.

It will be observed that when the motor D is in substantially the position illustrated in Figs. 1 and 2, the broach M may be put' I prefer to turn the broach M by means of motor D, pulley J and cooperating parts whenever a current of electricity is obtainable on the circuit of which wires E and e are members, as in that case it is only necessary to insert the broach M in the aperture K and swing the plate H and motor D into substantially the positions thereof which are illustrated in Fig. 8, thereby closing the switch in base B and causing the motor D to be actuated, thus turning the broach.

To operate the device the hook P is moved on bolt P to come underneath the leaf N, and into slot 0. The barbed end P is then brought out from said slot in a manner to draw fiber therewith from said receptacle 0, and said fiber is deposited underneath plate N. Said barbed end p is then placed underneath said plate N, and said broach is caused to rotate either by ribbon d or by pulley J, as preferred, and as hereinbefore described. When the fiber R is wrapped around the end of the broach it is removed from the machine and is ready for use.

I claim 1. A base, a fiber container and a fiber retainer on said base, an electric motor and a rotatable pulley mounted on said base to turn in a plane parallel thereto, an electric switch and a link connecting said motor and said switch, in combination with means to remove fiber from said container and to deposit said fiber under said retainer, and a broach, said pulley provided with a central aperture adapted to hold said broach, a driving connection between said apertured pulley and said motor, said motor, pulley,
